    Just got a new HD 48" Gravely zero turn. It has a 24 HP Kawasaki engine. When I got it home I checked the oil and it was milky in color, not the typical clear brown. To me this suggests water in the oil. Or - is this some kind of special break in oil? Doesn't even have 1 hour on it yet. Any thoughts?

    If it is liquid cooled I would be worried a little. If air cooled condensation or fuel in the oil could cause it. I would drain the oil and put fresh stuff in.

    I sent a message to Gravely so I will wait and see what they say. If I am not satisfied with their reply I will sample the oil and get it analyzed. If it ends up contaminated I will try to take it back to the dealer. It's not right spending $5K on a new mower to have this kind of problem (if it is a problem).

    I would carry it back to the dealer and show it to him now and ask for another mower.

    It's just condensation. Although the mower supposedly only has 1 hour on it, it has probably been started 100 times to move it around. Since the engine never got warm enough to burn off any condensation from each cool off period it accumulates moisture and makes the oil a little ugly. The dealer shouldn't have a problem changing the oil for you for free.

    I said supposed hours because hour meters are super easy to disconnect.

    To me it's a no brainer..Do yourself a favor and bring it back to the dealer you bought it from.

    Richard is exactly right. That's just condensation, the dealer's normally change the oil before delivery. It's pretty common to see that when they are moving the mowers out every morning so they can be seen. They should change it for you of course, but I wouldn't sweat it that much. Over time, condensation can get into any engine. This is why they say to change your oil every 3,000 miles OR every 3 months. Oil can get contaminated when an engine hasn't even been run.

    I can tell you straight up. If there is any water mixed in the oil whether it's from condensation or not. The metal parts including the bearings and crankshaft will have rust spots on them. NOT GOOD for a brand new mower. This will lead to premature engine failure. I'd want a different mower and if they couldn't provide that, I'd return it and get my money back.

    Dealer offered to come pick it up and change the oil & filter. I told him I wanted it changed out with another one. After talking to the powers that be he agreed to swap me out with a new one. Big relief for me. Thanks to all for the opinions.
